As always, there are lesser and greater individuals within a given species.
So you would have no problem with a "greater" human beating your family to death with a stick? Would you simply acknowledge his superiority?
You claim to be part of the greatest species, and yet you claim to exhibit the behavior of a curious caveman with a stick.
Hell, a lion doesn't needlessly kill the creatures that rummage around in his feces to survive, he respects the simple system around him. Kill to eat, to survive. Most of these "lesser" creatures find a natural harmony and don't just randomly kill small creatures than themselves for no reason.
You'd think being so advanced, we would get that, but what the hell.
